in the figure: the device comprises a high-pressure gas tank 1, a drain pipe 2, a control valve 3, an electromagnetic valve 4, a time relay 5, a silencer 6, a filter 7 and a sponge block 8.

Detailed Description

The utility model is described in further detail below with reference to the following figures and embodiments:

as shown in fig. 1 and 2, the automatic drainage device of the mining air compressor comprises a high-pressure air tank 1 of the air compressor, wherein a drainage pipe 2 is arranged at the bottom of the high-pressure air tank 1, an electromagnetic valve 4 is installed on the drainage pipe 2, a time relay 5 electrically connected with the electromagnetic valve 4 is arranged on the electromagnetic valve 4, and a drainage silencing assembly is arranged at the tail end of the drainage pipe 2.

The drainage and silencing assembly comprises a silencer 6 and a filter 7, the silencer 6 is fixedly connected with the tail end of the drainage pipe 2, and the filter 7 with different diameters is sleeved on the outer side of the silencer 6.

Sponge block 8 has been laid to drainage amortization subassembly's 7 bottoms of filter, and sponge block 8 can adsorb liquid.

The inlet end of the joint of the drain pipe 2 and the bottom of the high-pressure gas tank 1 is provided with a control valve 3, and the control valve 3 can be switched out for maintenance when the equipment is maintained.

The outer side of the water discharge pipe 2 is provided with an explosion-proof heat tracing band in a winding mode, so that the freezing phenomenon of pipelines in winter can be avoided.

The silencer 6 comprises a silencing pipe, and a plurality of silencing holes are formed in the silencing pipe, so that the drainage noise is reduced, and the working environment of workers is improved.
